Mosquito Control Without Chemical Insecticides

Most municipalities no longer conduct widespread, preventative spraying for adult mosquitoes, which is largely ineffective. Larval control mechanisms, and minimization of standing water for breeding are the main effective controls against mosquito populations.

In Bucks County, when problem areas arise due to inefficient breeding control, adult spraying is conducted, usually with Ultra Low Volume spray (fogger) application of Pyrethroids, such as Permethrin and PBO mixes, which are highly toxic to bees, other beneficial insects, and water-dwelling critters. There are many home methods that can be undertaken to reduce the risk of mosquito outbreaks, which are risk factors for diseases such as West Nile Virus.

Eliminate standing water from your property:

Drain pools when not in use, support with floats to minimize water accumulation on top of covers

When standing water cannot be eliminated, use safe, species-specific controls against larval mosquitoes such as commercial products containing Bti (Mosquito Dunks, etc.) to treat these potential breeding grounds . Birds and Bats can also provide a good source of control for adult mosquitoes. See Biological Controls for More Information

Minimizing Mosquito Bite Risk

avoid being outdoors between dusk and dawn

wear long clothing to cover exposed skin

use mosquito nets/screens or tents on porches and decks

use a personal insect repellent (Lemon Eucalyptus formulas are some of the most effective natural repellent alternatives to DEET formulas)
